Free Encryption tool
ClipSecure is a simple, secure, freeware text encryption utility that operates with the Windows clipboard, and therefore can be used within any text-based program and most email clients. It uses many industry-accepted algorithms, including the AES (Rijndael) standard, to provide maximum security. Encrypt and decrypt text with one keystroke, or manually control every step of the process. File encryption is also supported.

Just wanted to say it sure is good to see more and more freeware using true-blue algorithms. I was glad to see Rijndael as an option in this program you found. I'll jave to go check out the link now! Thanks for passing it along to all of us here.
